A male suicide bomber struck at a mosque in Maiduguri, capital of Borno state, on Wednesday morning.
The incident was said to have occurred while worshipers were observing the morning prayers.
According to Channels Television, the attacker retreated and later detonated the explosives, targeting those filing out of the mosque after prayers.
Only the suicide bomber was said to have died in the attack and four persons injured.
Soldiers and bomb experts, who re-enforced to the scene, dispersed the gathering crowd and fired at remains of the assailant, detonating two other explosives in the process.
A resident of Sulimanti, Mallam Ali Aji, who also was in the mosque when the explosion occurred, said “immediately after the blast, worshippers had to desert the mosque before men of the Civilian JTF and military arrived the scene and cordon off the whole area.”
